Left untreated, paralytic lagophthalmos may result in corneal dryness, ulcerations, and subsequent blindness. The most common nondynamic surgical solution is upper eyelid weight placement in a superficial, pretarsal pocket, carrying the risk of visibility, extrusion, and entropion. The authors present

Organic letters, 15(8), 1962-1965 (2013-04-12)

Metal-mediated rearrangements of 3-alkynyl flavone ethers are reported. The overall process involves 5-endo enyne cyclization to a platinum-containing spiro-oxocarbenium intermediate which may be trapped with methanol to produce spirodihydrofurans or further rearranged to afford either allenyl chromanediones or benzofuranones.
